Why the program listed below is not terminating. I am using gcc compiler in linux.
#include <stdio.h>
int main(void)
{
int c;
printf("Enter characters: ");
while((c = getchar()) != EOF)
putchar(c);
return 0;
}

This program will terminate just fine when the conditions are met. If you are on Linux press CTRL-D which is the EOF input. This will satisfy the condition and end the while loop.
while((c = getchar()) != EOF)
putchar(c);
This function will run forever, keeping your program from terminating until it gets a EOF input. Check how to send EOF on your native system. Once you input that the program will terminate.

If you are on windows press Ctrl-D which is the EOF input.... No, Ctrl-D works on Unix systems, such as linux or Mac/OS. on Windows you would type Ctrl-Z Enter
